Embodiment Construction

[0020] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0021] Such as figure 1 As shown, the structural representation of the solar drying device of the present invention is provided, which includes an oil tank 20, a circulating oil pump 19, a vacuum heat collecting tube 2, a reflective condenser mirror 3, a liquid-gas heat exchanger 13 and a drying device. The oil 21 and the circulating oil pump 19 are arranged on the outlet of the oil tank 20 for driving the heat transfer oil to circulate. The outlet of the circulating oil pump 19 is divided into two paths, one path is communicated with the vacuum heat collecting pipe 2 through the insulating oil pipe, and the other path is communicated with the liquid-gas heat exchanger 13 through the insulating oil pipe; the first valve 17 and the second valve 18 are respectively arranged in the oil tank 20 On the insulating oil pipe between the vacuum heat collecting ...

Abstract

The invention relates to a solar dryer which comprises an oil tank, an evacuated collector tube, circulating oil pumps, a drying system and a liquid-gas heat exchanger, wherein conduction oil is stored in the oil tank, the circulating oil pumps are arranged on oil outlets of the oil tank, and the oil outlets of the oil tank comprise two paths; reflective collecting mirrors are uniformly and fixedly arranged on the periphery of the evacuated collector tube and utilizes focused solar light to heat the conduction oil flowing through the evacuated collector tube; a temperature sensor for measuring the temperature of the conduction oil is arranged in the oil tank; the conduction oil achieving the temperature requirement flows through the liquid-gas heat exchanger and exchanges heat with process gas in the drying system, so that the process gas is dried. According to the solar dryer, after the high-temperature conduction oil exchanges heat with the process gas in the liquid-gas heat exchanger, the heated process gas is used for drying substances to be dried in a drying tube, for example drying tobaccos; thus, the utilization field of solar energy is widened.

Description

technical field [0001] The present invention relates to a solar drying device, in particular to a solar drying device which realizes high-temperature heating of heat-conducting oil by means of solar energy concentration to dry shredded tobacco. Background technique [0002] Energy is an important material basis for economic and social development. Since the industrial revolution, the world's energy consumption has increased sharply, fossil energy resources such as coal, oil, and natural gas have been consumed rapidly, and the ecological environment has continued to deteriorate. In particular, greenhouse gas emissions have led to increasingly severe global climate change, and the sustainable development of human society has been seriously threatened. Generally, when cigarette factories dry tobacco, they often use combustion furnaces to supply energy. The combustion furnaces basically burn oil or natural gas, which not only pollutes the environment, but also leads to energy cr...
